Sorry, I don't use FindBin (no one would ever guess that).

Once again we have an example of a feature that FindBin has but doesn't bother to export in a reusable manner (expanding symbolic links). 

    use File::Spec::Functions qw( rel2abs splitpath catpath );
    my $RealBin = $0;
    for( $RealBin ) {
        $_ = readlink($_) while -l $_;
        $_ = catpath( (splitpath rel2abs($_))[0,1] );
    }

or 

    use File::Spec::Functions qw( rel2abs );
    use File::Basename qw( dirname );
    my $RealBin = $0;
    $RealBin = readlink($RealBin) while -l $RealBin;
    $RealBin = dirname( rel2abs($RealBin) );

and evidence that File::Spec could use some additions (realpath, basename, dirname).
